Here's my short list of Tkinter weaknesses that I've struggled with:
1. Drag and drop. In fairness, there's a Tkdnd library and a bunch of
sample code on the internet. I haven't studied the examples I've
collected enough to figure out a simple, reusable way to do this. (Most
of my use cases are simply finding a way for users to re-arrange a row
of widgets packed or grided into a container)
The cross-platform binary TkDND extension by George Petasis (ably
wrapped for Python by Michael Lange) is an obvious choice here, but
Tkinter also has its own built-in tkdnd module, based on the canvas
widget, which is useful for simple things. It's not used much as far as
I can tell, but here is some documentation for it.

2. Ability to dynamically stretch and image in real-time. What I would
like to do is create widgets with a gradient background where the
background image stretches as the widget itself is resized.
PIL might help with this, I don't know.
3. Creating scrolling containers (I've been spoiled with Tkinter's
automatic layouts and don't look forward to manually placing widgets).
Doesn't PMW have some sort of scrolling widget container?
4. A way to show an auto-complete popup when one types in a Text widget.
There's an example of how to do this in the IDLE source code, I just
haven't looked for it yet.
Yes, you can probably look at IDLE as a good source for this.
My gripes with Tk:
1. Lack of a cross-platform printing solution. Every other
cross-platform toolkit does this, but no one has done it for Tk.
2. Lack of a modern HTML widget or an easy-to-use, cross-platform way of
wrapping one of the major browser platforms (Gecko, Webkit, IE). Lots of
partial solutions, but nothing that abstracts the platform differences
and presents a single API.
